Description

Technical Field

[0001] This utility model relates to the field of portable power banks, and in particular to an automatic cord retraction and repositioning structure for portable power banks. Background Technology

[0002] Most existing corded power banks have an automatic cord retraction function. When a cord is needed, it is pulled out from one side of the power bank; once charging is complete, the connector is unplugged and the cord automatically retracts into the power bank housing. This automatic cord retraction structure not only facilitates operation but also prevents the problem of lost cables.

[0003] The existing cable winding structure lacks an automatic repositioning mechanism during storage. When the cable is automatically wound in, the connector does not automatically attach to the power supply housing, requiring manual adjustment.

[0004] In view of this, this technical solution proposes an automatic cable retraction and repositioning structure for power banks. It adopts a cable stop near the end of the connector to enable automatic repositioning during cable retraction. The inertia of the cable retraction causes the connector to adhere to the power bank housing without the need for further adjustment, which also solves the problem of cable storage. In addition, this solution only makes minor changes to the cable and does not change the original main structure of the power bank. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the main objective of this invention is to provide an automatic cord retraction and positioning structure for power banks, aiming to solve the problem that existing power bank cords cannot be automatically retracted.

[0006] To achieve the above objectives, this utility model provides an automatic cord retraction and positioning structure for a power bank, including a connector that is connected to the main body of the power bank via a connecting cable. The main body of the power bank has a cable hole for the connecting cable to enter and exit. The connecting wire has a wire stop near the end of the connector. The wire stop has a diagonal block structure on the connecting wire, and its diagonal extension direction is towards the connector. The power bank body limits the connector by the cable stop, and causes the connector to automatically move closer to the power bank body when the cable is automatically retracted.

[0007] As a further embodiment of this utility model, the main body of the power bank is provided with a cable take-up groove for accommodating the connector, and the cable hole is opened on one side inside the cable take-up groove.

[0008] As a further embodiment of this utility model, a wire hole seat is provided on the wire hole, and the width of the wire hole seat is smaller than the width of the wire stop.

[0009] As a further embodiment of this utility model, the cross-section of the wire stop has a rhomboid shape with four parallel sides.

[0010] As a further embodiment of this utility model, the wire stop is a plastic component and is thermoplastically connected to the connecting wire.

[0011] The beneficial effects of this utility model are as follows: This technical solution incorporates a slanted, block-shaped cable stop near the connector end of the cable, extending diagonally towards the connector. This allows the power bank to automatically retract the connector and stably attach it to the main body during cable retraction, utilizing the interaction between the cable stop and the cable hole or socket. This completely solves the previous problem of the connector dangling and failing to automatically return to its original position after storage. The structure is simple and reliable, requiring no changes to the main power bank design. Only minor improvements to the cable achieve neat cable retraction, convenient access, and hassle-free operation, significantly enhancing the user experience. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] Please see the appendix Figure 1-7 , This technical solution provides an automatic cord retraction and repositioning structure for a power bank, mainly including a connector (20) connected to the power bank body (1) via a connecting cable (2). The power bank body (1) has a cable hole (11) for the connecting cable (2) to pass through. A cable stop (3) is provided at the end of the connecting cable (2) near the connector (20). This cable stop (3) has a slanted block structure, with its slanted extension direction facing the connector (20). The power bank body (1) uses this cable stop (3) to limit the position of the connector (20), and during automatic cord retraction, the connector (20) automatically moves closer to and adheres to the power bank body (1), effectively solving the problem that the connector (20) could not automatically return to its original position when the power bank cord was retracted. Users no longer need to manually adjust the position of the connector (20) after retracting the cord, making it more convenient to use.

[0026] Specifically, when in use (when charging), pull it directly out from the main body (1) of the power bank (similar to the use of a traditional power bank); after charging, unplug the connector (20), and the cable retractor inside the main body (1) will retract the cable (2) along with the connector (20) from the cable hole (11). The cable stop (3) has two functions: first, as a regular cable stop (3), it limits the connector (20) to the outside of the cable hole (11); second, when retracting the cable, it can make the connector (20) automatically move closer to the main body (1) of the power bank (meaning to attach or stick to). The principle that the cable stop (3) can automatically return the connector (20) to its original position is that the cable stop (3) itself is in the shape of a "slanted block". When the cable is retracted, the bottom (point) of the slanted block first contacts the periphery of the cable hole (11). When the cable is retracted, the slanted block is "flattened". Therefore, the connector (20) on one side automatically receives a force to one side during the "flattening" process, thereby driving the connector (20) to move towards the main body (1) of the mobile power supply, realizing automatic attachment. This not only keeps the appearance neat, but also avoids the problem of messy cables or the connector (20) being suspended.

[0027] Reference Appendix Figure 2 In a preferred embodiment of this utility model, the main body (1) of the power bank is further provided with a cable take-up groove (10) specifically for accommodating the connector (20), and the cable hole (11) is opened on one side inside the cable take-up groove (10). During the automatic cable take-up process, the connector (2) can be retracted through the cable hole (11), and the connector (20) is guided to accurately and stably enter and stop in the cable take-up groove (10). After being stored, the connector (20) is fixed in position and will not move or come out at will.

[0028] Reference Appendix Figure 6 In a preferred embodiment of this utility model, a wire hole seat (110) is provided outside the wire hole (11), and the width of the wire hole seat (110) is smaller than the width of the wire stop (3) on the connecting wire (2).

[0029] In practice, for example, during the automatic winding process, when the wire stop (3) is pulled toward the wire hole (11), the tip of the wire stop (3) is "misaligned" with one side of the wire hole seat (110) (at this time, one side of the wire stop (3) frames the outside of the wire hole seat (110), which can make it contact the wire hole seat (110) more smoothly and make it flip, reducing the jamming and friction during winding, and making the entire automatic return action of the connector (20) smoother and more reliable.

[0030] Reference Appendix Figure 3 , 6 7. A preferred embodiment of this utility model: The cross-section of the wire stop (3) of this solution is a rhomboid structure with four parallel sides, so that when it contacts the wire hole (11) or wire hole seat (110) during the wire winding process, each side can be evenly stressed, so that the flipping occurs more smoothly and stably, and the connector (20) automatically returns to the mobile power supply body (1).

[0031] Understandably, the rhombus structure is the preferred solution for achieving this flipping action, as it ensures the reliability and smoothness of the action. Of course, other shapes that can achieve similar guiding functions can also be used, but the rhombus structure shows good overall performance in manufacturing and actual use.

[0032] Reference Appendix Figure 2 , 3 6. A preferred embodiment of this utility model: The wire stop (3) in this technical solution adopts a plastic part structure and is firmly integrated with the connecting wire (2) through thermoplastic process. The wire stop (3) has sufficient strength to withstand repeated pulling when winding the wire. At the same time, its material is flexible and does not easily wear down the connecting wire (2) itself. Furthermore, the thermoplastic connection ensures that the wire stop (3) will not slide or fall off on the connecting wire (2), thus ensuring the long-term stability and reliability of the automatic return function.
